What is CLT / cross laminated timber?

CLT is also called "Cross Laminated Timber". The building material, which is also called cross laminated timber, is made of cross-laminated boards. The sustainable, solid boards are used as prefabricated parts for solid wood walls and solid wood ceilings of wooden houses. They can also be used for so-called wood-concrete composite ceilings.

Leidorf Holzbau specialises in the processing of cross laminated timber / CLT. We bind more than 100,000 square metres of CLT for our customers every year.
